Gears ticking under load only

Hello all

When i'm riding with the drive train under load it frequently sounds out of index (ticking like it wants to change gear). However, when i chuck it on the workstand to tweak the barrel adjuster it sounds ok- so i dont touch it. It's pretty frustrating.

I was wondering if this is a symptom of chain wear? I'd say the chain has done about 1.5k miles and cassette half that. I'll look into get a chain checker tool if this sounds suspect.

In addition, i'm running a 11-25 cassette but would like to swap for 11-28.... would this require a longer chain?

Thanks.

    no need to get a chain checker -> just use a tape measure http://sheldonbrown.com/chains.html#wear

    rear mech may be dirty/in need of lube, need adjusting, be out of alignment etc.

    if the current chain is the correct length, you need a longer one to fit an 11-28

    Try reindex your rear derailleur. Undo the bolt that clamps the derailleur cable and setup the rear derailleur as if newly installation. Your problem should go after that.
